Precautions for Design
DANGER
Always provide an interlock circuit outside of the programmable controllers system to ensure that
the entire system functions safely even in the event of data change, program change or status
control of a running programmable controllers from a peripheral device.
Predetermine the actions to be taken by the system if the communication fails because of a cable
connection fault, etc., during online operation of the programmable controllers CPU from a
peripheral device.
Precautions for Installation
DANGER
The 5VDC 0.4A current consumed by the EPU00E is supplied from the power supply module of
the main base unit.
Confirm that the current output from the power supply module is sufficient before connecting the
EPU00E.
If the output current is insufficient, the programmable controllers will stop operations, and all
output points will turn OFF.
Precautions for Installation and Handling
CAUTION
Use the EPU00E in the general specifications environment given in the manual.
Using the EPU00E in an environment not meeting these specifications, could lead to electric
shock, fire, malfunctioning and damage or deterioration of the product.
Make sure that foreign matter such as cutting chips or wiring scraps do not get in the EPU00E.
There is a risk of fire, faults or malfunctioning.
When connecting the EPU00E in the add-on method, plug the connectors securely and tighten
the clamp screws securely.
In the connection of the hand-held method, plug the RS-422 cable connector securely and

This section tells how to handle the EPU00E and explains the part names
4.1 Precautions When Handling the EPU00E
The following precautions should be taken when handling the EPU00E:
(1) Since the case is made of plastic, do not drop the EPU00E or subject it to severe shocks.
(2) Do not disassemble the case (doing so could cause a malfunction).
(3) When not using the EPU00E, handle the RS-422 connector as follows:
Attach the protective cap to the RS-422 connector on the rear side of the unit.
(4) Do not remove the connector cover of the extension interface on the upper side of the unit.
(5) Do not touch the RS-422 connector pins (doing so could cause a malfunction).
(6) Do not remove the cover of the EPU00E.
Do not loosen the screws that hold the cover (doing so could cause a malfunction).
(7) Always press the [CLEAR] key before disconnecting the EPU00E from an ACPU.
(8) Never use a cleaning agent such as thinner, alcohol, or freon.
(9) Press keys only with the fingers.
Using a sharp instrument, etc. could cause a malfunction.
Since the EPU00E beeps when a key is pressed, key operations can be confirmed by the
sound.
IMPORTANT
When designing the system, to protect the PC, make sure to provide a safety circuit outside that
system.

5. OPERATING PROCEDURES
5.4.3 Corrective action when a wrong key has been pressed
(1) Before pressing the [GO] key, press the [CLEAR] key, and redo the operation.
Pressing the [CLEAR] key clears the previously-input instruction and its device number,
and returns the EPU00E WRITE mode to its previous state. Then, the operation can be
redone.
(2) When the [GO] key is pressed, redo the previous operation.
REMARK
If the [CLEAR] key is pressed while the EPU00E is in the PARAMETER mode, processing
stops.
When the operation is continued, continue the pressing the keys as before.

Key operation procedure
and display contents
that follow the sample
operation
[Explanation]
(1) If the designated head step is in the middle of an instruction, processing
is executed assuming that the head step of the instruction has been
designated.
(2) When an instruction written to an ACPU is written to another instructtion, or when the previous number of instruction steps and the number
of instruction steps to be written are different, the step number is
shifted automatically with a later existing program.
And, when an additional operation after correction is continued, the step
number is also shifted automatically with a later existing program.
Detailed explanation of
each key operation
(3) Be sure to write the END instruction at the end of the program.
(4) The same coil is not checked in the WRITE mode.
When a check of the same coil is necessary, check using a program check
(see Section 6.9.3) in the OTHERS mode.
(5) Pressing the [SHIFT] and [WRITE] keys in the READ, INSERT, DELETE, MONITOR
(list monitor) or TEST (test of list monitor) modes enables writing of
an instruction after the cursor position(▶).
(6) When executing this operation when the ACPU is in the RUN state, execute
this operation after setting “WRITE ENABLED CONFIRM YES” in the OTHERS
mode (see Section 6.9.14).
IMPORTANT
When overwriting an instruction after creating a program using all the
program capacity registered in the ACPU parameters, write an instruction with the same number of steps. If an instruction with more steps
than in the instruction before overwriting is written, the step number
of the program which exists after the overwrite is shifted automatically,
and the end step instruction is deleted.

[Explanation]
(1) If the designated head step is in the middle of an instruction, processing is executed
assuming that the head step of the instruction has been designated.
(2) When an instruction written to an ACPU is written to another instruction, or when the
previous number of instruction steps and the number of instruction steps to be written are
different, the step number is shifted automatically with a later existing program.
And, when an additional operation after correction is continued, the step number is also
shifted automatically with a later existing program.
(3) Be sure to write the END instruction at the end of the program.
(4) The same coil is not checked in the WRITE mode.
When a check of the same coil is necessary, check using a program check (see Section
6.9.3) in the OTHERS mode.
(5) Pressing the [SHIFT] and [WRITE] keys in the READ, INSERT, DELETE, MONITOR (list
monitor) or TEST (test of list monitor) modes enables writing of an instruction after the
cursor position (▶).
(6) When executing this operation when the ACPU is in the RUN state, execute this operation
after setting “WRITE ENABLED CONFIRM YES” in the OTHERS mode (see Section
6.9.14).
IMPORTANT
When overwriting an instruction after creating a program using all the program capacity registered in
the ACPU parameters, write an instruction with the same number of steps. If an instruction with more
steps than in the instruction before overwriting is written, the step number of the program which exists
after the overwrite is shifted automatically, and the end step instruction is deleted.

[Explanation]
(1) If the designated head step is in the middle of an instruction, processing is executed
assuming that the head step of the instruction has been designated.
(Example) When step 106 is designated in the example on the previous page, steps 104
and after are displayed.
(2) When the ACPU is in the RUN state, processing takes longer than in the STOP state.
Therefore, wait until an instruction to be read is displayed.
(The processing time is proportional to the number of steps in a program.)
(3) If the [GO] key is pressed after pressing the [STEP NUMBER], the step number, and the
[GO] keys, the screen is scrolled up.

6. HOW TO USE EACH FUNCTION
[Explanation]
(1) The device and device number are searched from step 0 by pressing the [GO] key after
setting device and device number. And then, the detected step is displayed. Thereafter, an
instruction is searched from the following step by pressing the [GO] key, and the detected
step is displayed. When an instruction cannot be detected even if it is searched to the END
instruction, PROGRAM NOT FOUND is displayed.
* Changing input data before pressing the [GO] key, data can be changed by the following
operations:
・After pressing the [CLEAR] key, reenter the correct data.
・When changing a device and a device number , reenter the correct data.
(2) When reading by using device numbers, a designated device modified by indexes Z or V
(when an A2A or A3ACPU is used: Z, Z1 to Z6; V, V1 to V6) is also read as the
corresponding device. (See sample operation 4).)
If a device number with indexes is designated, a DEVICE ERROR occurs and it cannot be
read.
(Example)
STEP NUMBER → D → 0 → Z → GO
DEVICE ERROR
(3) When reading device number “CD” of link relay (B), input [B], [0], [C] and [D]. If only [B], [C]
and [D] are input, a BCD instruction is read.
(Example)
STEP NUMBER → B → 0 → C → D → GO

When a check of the same coil is necessary, check using a program check (see Section
6.9.3) in the OTHERS mode.
(6) Pressing the [INSERT] key in the READ, INSERT, DELETE, MONITOR (list monitor) or
TEST (test of list monitor) modes enables inserting of an instruction after the cursor
position (▸).
(7) After pressing the [STEP NUMBER], step number, and [GO] keys, press the [GO] key to
scroll the program up.
(8) When executing this operation when the ACPU is in the RUN state, execute this operation
after setting “WRITE ENABLED CONFIRM YES” in the OTHERS mode (see Section
6.9.14).
IMPORTANT
When overwriting an instruction after creating a program using all the program capacity registered in
the ACPU parameters, write an instruction with the same number of steps. If an instruction with more
steps than in the instruction before overwriting is written, the step number of the program which exists
after the overwrite is shifted automatically, and the end step instruction is deleted.

6. HOW TO USE EACH FUNCTION
[Explanation]
(1) Not only the program is read by an operation that is the same as the read by the step
number, but the conductivity state, ON/OFF state of a device contact, and the current value
of a device are also monitored.
However, the conductivity state of an A0J2CPU, A3HCPU, A3MCPU, A2ACPU(S1) and
A3ACPU will not be not displayed.
(2) Explanation of display contents
(a) Monitoring conductivity states
Checks whether an instruction such as OUT, MOV, BCD, BIN and operation instruction
is executed.
The conductivity state is displayed on the left side of the instruction.
To display the conductivity state, set the conductivity state display setting (see Section
6.9.15) to “YES” in the OTHERS mode. When the power supply is turned ON, the
conductivity state display is set to “NO”.
Conductivity state display
When it is conductive, “■” is displayed;
when not conductive, it becomes blank.
However, when a conductivity state display
and the cursor overlap, “▶” indicates conductivity, and “▶” indicates non-conductivity.

6. HOW TO USE EACH FUNCTION
[Explanation]
(1) Monitoring by designating 1 point
(a) The ON/OFF states of bit devices (X, Y, M, L, S, B) can be monitored. Monitoring of an
offline switch state can be also executed. (There is no offline switch function in the
A0J2CPU, A2ACPU, A3HCPU, A3MCPU and A3ACPU.)
An offline switch is displayed by using the Help operation or offline switch setting of the
TEST Mode. (See Sections 6.6.5 and 6.7.5.)
(b) The current values of word devices (D, W, R) can be monitored.
(c) The set values, current values, and ON/OFF states of contact timer counters (T, C) can
be monitored.
However, when the set value is set at a word device, a device number is displayed.
(d) The number of monitored points is 4 max.
However, only 4 points of a bit device, timer/counter, or word device can be monitored.
Monitoring cannot be executed by mixing bit devices, timers, counters, and word
devices.
(2) Monitoring by designating multiple points
(a) Designation of multiple bit devices
Monitoring the ON/OFF state of bit devices is executed in units of 8 points.
When a set bit device number cannot be divided by 8, it is monitored automatically by
device number in units of 8 points. For example, if multiple M10 are designated, M8 to
M15 are monitored.
(b) Designation of multiple word devices
These are handled as 32-bit data, and a current values are monitored.
(c) The number of points to be monitored is 4 max.
However, only 4 points of a bit device or word device can be monitored.
Monitoring cannot be executed by mixing bit devices and word devices.
(3) Operation that monitors a serial device number
(a) If the [GO] key is pressed after inputting a device number, the following device number
is displayed.

6. HOW TO USE EACH FUNCTION
[Explanation]
(1) Turn ON a device number set by pressing the [SHIFT]→[SET]→[GO] ([1]→[GO]) keys.
Turn it OFF by pressing the [SHIFT]→[RST]→[GO] ([0]→[GO]) keys.
(2) As for forcible set/reset operations when the ACPU is in the RUN state, program execution
has priority.
Therefore, even if forcible set/reset is executed when an instruction using a correspondent
device is being executed, the state only changes for a moment and returns back.
(3) Even if a process input is OFF, when input (×) is set forcibly, an ACPU executes the
operation processing as ON.
And, even if input (×) is reset forcibly when a process input is ON, the PC CPU is
processed as ON.
If input (×) was set, be sure to reset it after the test operation has been completed.
(4) As for special-function modules, some of the Y numbers cannot be set/reset.
(5) Special relay (M) is controlled by the OS of the CPU. Operate set/reset of special relays
after checking the contents utilizing the User's Manual of the connected ACPU.
(6) Pressing the [SHIFT] and [TEST] keys in the READ, WRITE, INSERT, DELETE, and
MONITOR modes (list monitoring) enables the test operation of the designated device
indicated by the cursor(▶).
IMPORTANT
Be sure to reset devices set by this operation before operating.
Batch reset can be executed by using the CPU's reset switch.

6.8 Parameter Setting
This section explains how to clear all parameters of an ACPU and explains how to set the
program capacity, file register capacity, etc.
Only those parameters that can be set by the EPU00E are given on the parameter sheet
attached to the APPENDIX. An A6GPP/A6PHP (SW
GP-GPPA), IBM * PC/AT (SW
IX-GPPAE) and A7PHPE (SW
RX-GPPAE), etc. are necessary for setting of other
parameters.
Since this manual only explains parameter setting operations, determine the setting contents
of parameters by referring to the Programming Manual of the particular ACPU.
The operation given below illustrates parameter setting.
*IBM is a registered trade mark of the International Business Machines Corporation.

(3) If the key word is registered, parameter all clear cannot be executed.
REMARK
The parameter in the EPU00E is set to a set value read from ACPU when starting up the
EPU00E.
POINT
・When executing parameter all clear, if the key word registered in the ACPU is unknown, see the “PC
memory all clear” operation shown in Section 5.1.3. And then, clear (delete) the unknown registered key
word.
If “PC memory all clear” is executed, all other user data (such as sequence programs) will also be
cleared.

6. HOW TO USE EACH FUNCTION
[Explanation]
(1) The EPU00E starts a program check and checks “dual coil”, “instruction code error”, and
“END instruction missing” of all instructions in the range from a designated step to the END
instruction of a sequence program written to an ACPU. (Therefore, checking will take some
time.)
(2) When a program check is completed normally, the step number of the END instruction and
“END” are displayed.
(3) When an error or fault is detected by a program check, the step number where the error or
fault occurred and the message that corresponds to the fault contents are displayed, and
the program check is interrupted.
1) Press the [GO] key to execute continuous program checking. A program check is started
from the step next to a stopped step.
2) When modifying error or fault contents detected by program check, press the [READ]
key, or [SHIFT]→[WRITE] keys when an error or fault is detected (when a program
check is interrupted).
The program of the step number where an error or fault occurred is displayed by
pressing the [READ] key, or [SHIFT]→[WRITE] keys.
Therefore, correction can be done easily. When an error or fault occurs, modify the
sequence program as follows:
Designated dual coil······················· Modify the program if necessary.
Instruction code error ····················· Overwrite the same instruction. (Rewrite)
END instruction missing ················· Add it.
3) Use the following methods to continue the program check after modifying the program:
Method of continuing a program check from the stopped step
······················································· Select “2: PROGRAM CHECK” from the OTHERS
mode, and press the [GO] key. (The interrupted
number of steps is displayed.)
Method of continuing from the designated step
······················································· Select “2: PROGRAM CHECK” from the OTHERS
mode, input the designated step number, and press
the [GO] key.
4) Pressing the [END] or [CLEAR] key returns to the “2: PLC CHECK” menu.

6. HOW TO USE EACH FUNCTION
IMPORTANT
(1) Writing to the EEPROM when the CPU is in the RUN state is disabled.
(2) As for writing when the CPU is in the RUN state, only writing that can be corrected by one
instruction can be executed. Be especially careful when the ladder configuration is being
changed by writing when the CPU is in the RUN state.
Example)
When a ladder is added by writing when the CPU is in the RUN state
M100
M110
M100

When the ladder has been added, the configuration of a ladder has now been changed as shown

(3) When writing when the CPU is in the RUN state is executed, the switching instruction [CHG] for
sub-programs and main programs is automatically prohibited. However, an when A3ACPU is
used, it is executed.
When writing when the CPU is in the RUN state has been completed, the prohibition of the [CHG]
instruction is automatically canceled.
(4) When changing a program by using this function, do not operate the RUN-STOP-PAUSE-STEP
RUN switch.
Doing so can destroy the program.
(5) Writing when the CPU is in the RUN state cannot be executed to the PC CPU of another station
by setting the PC number on data link system.
(6) If there is a pulse instruction (PLS,
P) in the program when writing is executed while the CPU
is in the RUN state, the CPU executes or does not execute the pulse instruction unconditionally
after completing writing when the CPU is in the RUN state. When it is not necessary to execute a
pulse instruction, do not change any ladders while the CPU is in the RUN state.
